Lock
DraftFour rings, each with a symbol and a lamp. Symbol and lamp colour give the digit to set on each ring, then ENTER.
Checked with game version 1.1.0
How to recognise it
Four rotating rings with Braille digits, a symbol printed under each ring, a lamp per ring and an ENTER button. The symbols are the same ten shapes as on the Symbol module. New in the MAYDAY update.
Procedure
Turn each ring until you feel the digit given, say "ring one on four" before moving to the next, and press ENTER only after all four are confirmed.
Common mistakes
Mixing up filled and outline star, or the two triangle shapes. Name the outer shape first.
Using the Symbol module's colour table instead of this one. Same shapes, different table.
Solver
Enter what you see on the bomb and get the action for the current state.
